The last time Dayton saw measurable snow was before the official start to winter. On Dec. 7, 0.1 inches of snow was recorded and 0.2 inches came on Dec. 8.

In a month where we expect to see 4.8 inches of snow only 0.3 inches fell over two days. 2021 ranks as the fifth least snowiest December.

This year we saw more rain than snow during a very mild December.

Dayton saw 4.49 inches of rain ranking at the ninth wettest December on record.

A warm and wet pattern is expected during a La Nina Winter.

A cold snap is still possible. One dip in the jet stream and the Arctic air will be in the Maimi Valley. If the moisture is there when the arctic air is, we can still end up with high snowfall totals.

El Nino Southern Oscillation records are kept dating back to 1950. Since then Dayton has recorded above-normal snowfall during a La Nina Winter 71% of the time. At least a trace of snow has been reported in April 80% of the time.
